What is Software process framework And, Umbrella activities

Image
  ❖ Software generic process framework activities .   A process framework establishes the foundation for a complete software process by identifying a small number of framework activities that are applicable to all software projects, regardless of their size or complexity. • In fig each framework activity is populated by a set of software engineering actions. A collection of related tasks that produces a major software engineering work product. • Each action in process framework is populated with individual work tasks that accomplish some part of the work implied by the action. 1. Communication: Communication framework activity involves heavy communication and collaboration with the customer,encompasses requirements gathering, data gathering and other related activities. 2. Planning: Planning activity establishes a plan for software engineering work that follows. Planning describes the technical tasks to be conducted, the resources that will be required, schedule, and the risks...

What is Java Virtual Machine and Command Line Arguments

                                              Java Virtual Machine



All language compiler translate source code into machine code for a specific computer .Java compiler also does the same thing ,Then how does java archive architecture neutrality ? The answer  is that the java compiler produces an intermedia code known an bytecode for a machine that does not exits , This   is  a machine is called the java virtual machine and it exits only inside the computer memory , It is a simulated   computer within the computer and does all major machine of a real computer, illustrates the process of compiling a java program into byte code which is also referred to as virtual machine code 

The virtual ma chine code is not machine specific code (known as machine code) is  generated by the code interpreter by acting as an intermediary between the virtual machine and the real machine as shown in Remember that the interpreter is different for different machines.

 Illustrate hoe java work on a typical computer , The java object framework (Java API) acts as the intermediate between the user the virtual machine which in turn acts the intermediary between the operating system and the java object framework 


         .Command Line Arguments

There may be occasions when we may like our program to acts in a particular way depending on the input provided at the time of in the executions . This is archived in java program by using what are the known as command line argument , command line argument are para meter that are supplied to the application program at the time of invoking it of execution , It may be recalled that program was for  invoked execution of the command line 

.Here, we have not supplied any command line argument. Even if we supply argument, the program does not know what to do with them.
 We can write Java programs that can receive and use the argument provided in the command line. Recall the signature of the main ( ) method used in our earlier example programs: 

As pointed out earlier, is declared as any array of string  known as string objects .Any argument provided in the command line at the time of execution are passed to the array its elements , We can simply access the array element and use them in the program as we wish .

What is Constants, Variables, and Data Types

Image
                                          Constants   Constants in java refer to fixed values do not change during the execution of a program , Java support several types  of constants as illustrated. .Integer  Constants      An integer constant refer to a sequence of digits , There are three types integers .namely decimal imager octal integers and hexadecimals integers . Decimal integers consist of a set of thing preceded by an optional minus sign Valid of decimals integer constant  .Variables  A variable is an identifier that denotes a storage location seed to store a data value unlike constant that remain unchanged during the execution of a program , a variable may take different values at different times during the execution of the program ,we had used several variable for instance , we used variables length and breath to store the values o...
